Usually it is by pushing the switch on the wall into the down position. If that does not work, turn the bulb until it does not make contact and fix the switch.
the materials required are 1. bulb 2. IC 3. any thing that u need to make it.... Just do it guys...............

In a theoretical ciucuit, a switch is not essential. What is needed is a source of electricity.

You can make music come on with a light switch the same way you can make a light bulb come on - plug a radio into the switched outlet.
to make a torch you need batteries (obviously), a switch (you can buy a standard switch or make a pressure switch out of foil and cardboard), a light bulb, wires (3 if you are using any kind of switch) and a housing (something to hold the batteries, wires, light bulb etc. together). I would also recommend using a light bulb holder and wires with alligator clips (if you dont have solder) as these make the construction more sturdy. they may increase bulk but they are worth it especially as it is easy to replace the bulb and there is no solder needed therefore nothing has to be broken to replace anything.
A Switch is a device used to make or brake an electronic circuit for a purpose such as starting a fan, lighting up the bulb etc.
Circuit Electrons flow form the positive end of the battery through the wire connecting the positive terminal to a switch. The other end of the switch is connected to one terminal on the bulb, the other terminal of the bulb is connected to the negative end of the battery. No electrons (current) flows as long as the switch is open. Once the switch is closed and if the battery has enough voltage and current capacity to make the filament in the bulb glow, then the bulb emits light (together with wasted heat). If the switch is open, no current flows through the entire circuit and the bulb does not glow.
